art to which it appertains to malte and use the same.

This invention relates to brakes. One of the .objects thereof is'to provide efficient and practical means adapted to mount a brakeshoe upon a. brake-head, irrespective ofthe types of either of these parts, and more especially to provide means for adapt-ing a widely used but somewhat antiquated type.

of head to support shoes of the most modern and approved character.

Another object is to provide strong and simple shoe-supporting means which shall be adapted to be assembled witha minimum of effort in the most confined and inaccessible locations.

Other objects will be in part obvious and in part pointed out hereinafter.

T he invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will bc exemplified in the device hereinafter described', and the scope of the application 'of which will be indicated in the following claims.

ln the accompanying drawings wherein is shown one of various possible embodiments of my invention- Figure l is a side elevation showing the same in operative position. Fig. 2 a perspective showing a shoe with a part of a composite supporting-member positioned thereon and illustrating the method of assembling these parts.

Similar reference characters refer to similar parts throughout b oth views of the drawing.

This invention will be most readily-un-A derstood. if the following facts are borne 1n' mind: Certain well known, but at present antiquated types of break-heads have found a broad application and are nowin extensive use. These heads require the use of shoes having connecting means complementaryT to those of the head and tht s require the use of relatively old and .inefficient types of shoesr' In order to bring into use the most modern types of brake-shoes," it has been found necessary to discard the former types 55 oi' break-heads and thus consign large and expensive equipments of this character to' the scrap heap. It may also be noted at this point that after the parts of the truck and the brake rigging are assembled, the brake- 6o shoes and heads are often positioned in the most cramped and inaccessible locations, and no renewal or repairing of these parts can be accomplished wit-hout marked inconvenience and considerable outlay of time and labor.v 65

'The above and otherv defects are eliminated and many positive advantages attained in constructions of the nature of that herein after described.

Referring now to the Fig. l of the accom- 7o panying drawings, there is shown a brakehead 1 which, it may be assumed, is typical of certain forms ofheads which have been in wide use for a considerable'period of years. This head comprises the flanges 2, adapted to 7 5 be secured to the brake-beam, and upon its forward surface is provided with a recess 3 and abutments 4 and 5. Upon this head .is mounted a member 6, which may be termed an"intermediate heat The latter member So` is preferably formed in two parts, having upon their rear surfaces the projecting per-l forated lugs 7 adapted to fit within the recess 3, within which they are secured as by the pin orkey 8. `85

The outer ends of the component members 9 and 10,' assuming thatmember 6 is of the composite type which best embodies certain features of my invention` take against the abutments 4 and 5 respectively and are thus, 9o held firmly in position.

The forward surface ofthe intermediate head is provided, with regard to the broader aspects of my invention, with means adapted to make connection with a shoe of any ap- 9 5 proved type, thus permitting the use of a modern type of shoe without the' sacrifice of anyportion of the equipment formerly 'in use, other than the shoes which are displaced. lith regard to certain more specific features roo of 'my invention, T adapt theforward surfaces of the parts 9 and 1() to make connection with a shoe il provided upon its rear surface wi-than undercut tenen 12 tapered from its central portion toward each of the m5 ends of the shoe.' This 'member is preferably in two portions, asshown in the drawings so as to adapt the same to nerform certain Vthe present invention, but if desire shoe. may-be made in a sin stacca functions not immediately concerned with intended t-o cover all fof the generic and sped, the glc piece. rlenon 12 is adapted to rest within' corresponding mortises' 13 and 14 in the forward faces of the members 9 and 10 respectively, thus mounting the shoe. upon the intermediate Y head and through this part upon the head 1.

In order to avoid the chance of ambiguity in the meaning of certain of the claims, it may here be noted that by the term "dissimilar,

confined positions.

as used throughout this specificationand the `following claims, is meant a characteristic by virtue of whichthe parts described are' of types differing in some respect. Thus, in regard to connecting means between the intermediate head and the parts secured thereto, vbringing out a dominant feature of my invention 'whereby lprovide means for the elii cient use of shoes of any desired type in connection with heads of any type with the above noted advantages.

The method of use of the above described embodiment of my invention is as follows: Assuming that it be desired to mount the shoe 11 upon the head 1, the parts of the intermediate head are separately slipped over the tenori 12, and the lugs 7, being thus brought together are inserted in the recess 3 and secured in place by the key 8. If it be desired to use a multiple shoe, the same is mounted in a similar manner, the outer shoe being first secured to the shoe 11 by separately slipping over the tenon formed thereon, itbeing assumed that this shoe is identical with that shown, a part or parts provided with the mortise or recess indicated indotted lines at 15. The intermediate head is then placed in position upon the shoe 1 1, as i above described, and mounted upon the head 1 in the above manner.

lt will thus be seen that Ihave provided simple and etlicient means adapted to accomplishthe several objects of my invention,

and that thisl means is of the most inexpensive construction -and thoroughly reliable action.y The several parts are secured in place with a minimum of effort and 'may readily be detached or replaced in the most The ent-ire construction is of an essentially practical character, moreover, and is well adapted to meet the requirements of the severe conditions incident to the use of apparatus of the character of that with which this invention deals.

Asy manychanges could be made in the above construction and many apparently widely different yenibcdiments of my invention could be made without departing from the scope thereof, i intend that all matter contained in the above description or shown in the accompanying .drawings shall b e interpreted as illustrative and not in a limiting sense. l desire it also tobe understood that the language used in the,

l i l l i l cific features of the invention herein dcscribed and all statements of the scope of the invention,.which, as a. matter of language, might be said to fall therebetwcen. i j

Certain features herein shown and dcscribcd are shown, described'and claimed in my Patent No. 846,481, dated March 12, 1907, and, accordingly, are not claimed herein.
